The credit card info is called "level 3 data" and they in some cases have line item by line item detail. Not just "spend $24.89 at Meijer store #349" but each individual thing, e.g. you bought 2 avocados.
- axaxs 8y agoIs that recent? I just started getting it this year. Is there a way to opt out?
- patrickg_zill 8y agoFrom what I know, it started a few years ago; but not all big stores had the equipment in place to send it (the cc processors give them a discount for sending the line-item level 3 data). With the advent of the chip and pin cards in the USA, it seems logical that just about everyone upgraded to equipment that does support it; which might explain why you are only seeing this in the past year.
- axaxs 8y agoSo, this seems a little opposite of what I meant. Naive me always assumed I pay with a card, the store gets my cc info to charge and we part ways. I'm getting in the mail ads from Meijer, for items I buy frequently. This tells me they were able to extract my home address and name from my credit card. Is that accurate?
- thelastidiot 8y agoYes, these data are all available, if you are willing to pay to get those.
- 18pfsmt 8y agoI worked for the largest merchant acquirer ~11 years ago, and we were collecting SKU-level data for Wal-mart at that time.
- lotsofpulp 8y agoI noticed that now when my employees buy from staples.com, my AmEx statement will show everything they bought. From a manager's perspective, it's kind of awesome because you don't need to keep track of little receipts.
- dizzant 8y agoIs this data available to mortals? I don't even have digital itemized receipts for credit card purchases, and it's my purchase!
- propogandist 8y agoMastercard and Visa [1] sell this data in aggregate to firms via brokers like Bluekai, to allow for ad-targeting. I don't believe it'll be feasible to purchase just one person's purchase data [easily], but if you knew who you wanted to get to, it should be possible to narrow the targeting to get to them [1] http://www.oracle.com/us/solutions/cloud/data-directory-2810741.pdf http://www.oracle.com/us/solutions/cloud/data-directory-2810...

- discordance 8y agoWouldn't a GDPR request to Visa or MasterCard in the EU get me this data?
- black_puppydog 8y agoThat's what I was thinking. Would be awesome for personal budgeting...
- namibj 8y agoWell, they have to provide it digital, if they already have it digital. So yeah. Anyone wanna integrate the format they can deliver with e.g. GNUCash or so?
- greglindahl 8y agoHow does this work with Apple Pay, which doesn't tell the retailer who the consumer is? Does the retailer sell the info, or the credit card company?
- macintux 8y agoWondered about that too. Apparently Apple Pay does use the same artificial CC number with each payment (maybe only with the same merchant?) so it's still possible to have your purchases tracked over time, even if they don't know who you are.
- jimjimjim 8y agousually there is only space for group ids of items rather than individual item details. but i guess it might be different for different acquirers. the purpose of loyalty cards is that the messages are usually acquired or processed on non-bank systems so they can go into much greater detail and include individual sale item details
- bb101 8y agoI wonder if the credit card companies have access to line-item level 3 data if we use ApplePay?
